Functions The Functional Description of the CU-XE communication unit is provided separately. The main functions are briefly summarised below.

2.4.1

Ethernet interfaces The CU offers two Ethernet interfaces conforming to IEEE 802.3 standards applicable to both 100BASE-TX and 10BASE-TX. Depending on the Ethernet interface used, the CU offers various services.

2.4.1.1

Management interface The CU provides an Ethernet interface that is intended for the management of the device. It provides access to the device using a standard web browser (Web UI) for the purposes of changing the configuration and gathering diagnostic information. The interface uses a secure web interface based on HTTPS (Hypertext Transfer Protocol over Transport Layer Security). For backwards compatibility, the web interface is also accessible over unencrypted HTTP (Hypertext Transfer Protocol).

2.4.1.2

Main interface This network interface provides access to IP-based services and, in addition, is also a client for IP services depending on application requirements. Examples of IP services include: 



Passthrough and bridging are protocol independent

Note It is recommended to verify the suitability of any non-listed protocol that you intend to use. Landis+Gyr technical support may be contacted for support.

See the description of services. Each service is described in section 5 “Operation”.

2.4.1.3

Network bridging Activating the bridge will aggregate both Ethernet interfaces and connect both network segments transparently. It does not justify the installation of a dedicated Ethernet switch with its own power supply.

2.4.2

RS-485/RS-422 interface The RS-485/RS-422 interface is a serial, bi-directional, full-duplex, differential interface. The interface includes user configurable bias and termination resistors. A typical application is to create a multi-drop bus, where multiple devices can share the communication channel. For example, up to 31 E650 meters can be connected to the RS-485 bus configured as the bus master, and they can be read remotely using the Ethernet interface. To configure the RS-485/RS-422 bus, termination DIP switches can be used. Legends for the scenarios below: 1

Installation/uninstallation

4.1

Installation in a meter

No voltage to the meter during installation In order to avoid hazardous electric shocks, make sure that there is no voltage applied to the meter when installing the communication unit. Contact with live parts is dangerous to life. Disconnect the meter from the power supply as described in the meter User Manual.



Excessive number of power failures reduces life of product The CU writes to its internal FLASH memory every time there is a power failure. This type of memory has a life expectancy of approximately 100,000 write cycles. This is not a guaranteed value. For a life of 15 years this amounts to approximately 15 power failures per day. Exceeding this limit may shorten the useful life of the product.



E65C CU-XE communication units can be used in E650 (from Series 3 FW version B30 upwards), S650 and E850 electricity meters or in CU-ADPx adapters The CU is designed to be interoperable with meters existing at the time it was designed. Once the meter is obsolete and is replaced by a newer version of the product, interoperability testing stops. This means that older meters that have been in the field for a number of years should not be used with new CUs even though they can be inserted into the meter.

Install the communication unit in a meter as follows: 1.

Make sure that no voltage is applied to the meter.

2.

Remove the utility seals on the front door and terminal block cover.

3.

Open the front door and remove the terminal block cover.

Connecting the communication unit

4.2.1

Connecting the RS-485/422 interface Insert the connecting cable with the RJ45 connector to the socket labelled RS485/422 in the communication unit until the connector engages. Connect the other end of the cable to the nearest unit of the RS-485 multiple connection. If the RS-485 interface is provided with two internally connected RJ12 sockets (e.g. CU-B2), the next extension of the RS-485 bus can also be provided with an RJ12 plug. If, however, only one RJ12 socket is present (e.g. CU-XE) the extension for the RS-485 bus must be formed with an external splitter.

Connecting multiple communication units

External wiring of RS-485 In order to function correctly, all 3 wires (data a, data b and Common GND) must be connected. RS-485 operation with only 2 wires (without common GND) is forbidden as the RS-485 interface may not function correctly or may even get damaged.

4.2.2

Resealing the device After all connections have been made to a CU-XE, you can replace the terminal block cover and seal it with a utility seal.

4.3

Commissioning and functional check The CU-XE communication unit should be taken into operation as follows (see also section 5 “Operation” for a detailed description of the LED states): 1.

After switching on the mains voltage, a red boot LED is blinking. When the CU-XE communication unit is ready for operation, the LED switches to green. When the Ethernet connection is made, the running LED is illuminated.

2.

A remote readout of meter data via Ethernet should be performed as a functional check, if the CU has been appropriately configured.

3.

If a multiple connection to further devices is present, check that they are working as expected.

Ethernet ports

The upper part of the screen indicates the current address information including MAC, IP address, Netmask, Broadcast and Gateway. Settings can be changed, e.g. you can switch the main interface on and off (“Interface enabled” for on). Bridging functionality can also be activated. Under IPv4 Setup, either the main interface or the bridge can be configured depending on the other settings on this page. If the bridging is enabled, the management port is not accessible over the standard IP or device ID see under cross ref 5.1.1. as the management port has the same IP address as the main port. The IP address can be configured manually in case the IPv4 setup is not set for automatic IP addressing over DHCP. For the main port the manually inserted IP address cannot refer to the same subnet as used for the management port.

After changing the settings for Ethernet ports, first save the changes by clicking Save. To activate the new configuration restart of the device is required. Restart can be accomplished using the Reboot button on the left.

Operation

5.1.2.1

Bridging Bridging over Ethernet interfaces allows you to connect several CUs transparently, without using an external switch. Therefore, it is a viable option for meter room applications. Bridging has been tested with up to 20 CUs. The network is a linear topology and it is assumed that it is loop free since there is no Spanning Tree Protocol support implemented in the bridges. For more complex networks, a star topology, where only one CU is connected per link, is recommended.

5.1.5

Forwarding (passthrough)

To be able to establish a “direct” connection between devices on different ports (serial and/or Ethernet), the CU provides a passthrough functionality. Application level data received on one interface is forwarded to one or more other interfaces (and vice versa). Using this approach, the device is capable of handling every data transmission (independent of any protocol language) on the configured ports. In this sense the passthrough component acts as a fully transparent media converter. The CU contains several different ports that can be used for passthrough: D000062528 en d – E65C CU-XE – User manual

Serial ports (RS-485/RS-422 or RS-232)

Internal port to the base meter

Ethernet bridging is meant to be used for forwarding using Ethernet ports (passthrough from Ethernet to Ethernet is not possible). The passthrough feature can be used in a number of different ways. See the example below.

Remark: Passthrough is not protocol-aware, i.e. every use case that does not require actions on the CU itself is supposed to be supported. Every protocol requiring actions (such as transmission speed switch at HDLC Mode E) is not supported. Passthrough works like a bus with several attached ports. The number of ports attached to a bus is limited by the amount of available ports only. Traffic received from one of the connected ports is forwarded to every other port. This also implies that the slowest port defines the bus-speed, which might have an impact on the timing behaviour.

It is possible to have up to 4 busses configured to work in parallel. If forwarding is being used to read out the base meter, the following protocols are supported:

Service

6.1

Troubleshooting When a fault has been detected in the system, check the following points regarding the interfaces: 1.

Is the mains voltage present (meter LCD is working)?

2.

Has the maximum permissible ambient temperature been exceeded?

3.

Is there any visible damage to the installation?

4.

Check the status of the LEDs according to section 5 “Operation”.

If none of these steps resolves the problem, the communication unit should be removed and sent to the designated service and repair centre.

6.2

Repairing the communication unit Communication units can only be repaired by authorised service and repair centres (or by the manufacturer).

Meters must not be operated without a communication unit or “dummy”. For safety reasons, the meter must not be operated without a communication unit or a “dummy” communication unit.

If repairing the communication unit is necessary, use the following procedure: 1.

If installed, remove the communication unit and install a replacement communication unit. If no spare unit is available, a “dummy” unit must be used.

2.

Describe the problem as accurately as possible and state the name and telephone number of the contact person in case of inquiries.

3.

Pack the communication unit carefully to ensure it will not suffer any further damage during transport. Use the original packing materials, if available. Do not enclose any loose components.

4.

Send the communication unit to the designated service and repair centre.
